5 Essential Tips for Protecting Your Excavator Hydraulic Pump When Using a Breaker Attachment
Excavators equipped with a breaker are powerful tools for breaking and demolishing concrete and other hard materials. However, this intense activity puts a lot of strain on the excavator's hydraulic system, specifically the hydraulic pump. As a result, proper maintenance and protection of the hydraulic pump are critical for the longevity of the excavator. In this article, we will explore five ways to protect the excavator hydraulic pump when the excavator is equipped with a breaker.
- Proper Engine Speed
When operating an excavator with a breaker, it is essential to maintain the correct engine speed. The breaker has low requirements on working pressure and flow rate, so it can work with a medium throttle. However, excessive engine speed can cause the hydraulic oil to heat up abnormally, leading to significant damage to the hydraulic system. Therefore, it is crucial to maintain the correct engine speed and avoid overheating the hydraulic oil.
- Correct Buttering Posture, Frequency, and Quantity
Proper buttering is crucial when operating an excavator equipped with a breaker. It is essential to add lubricating grease when the steel drill is pressed straight into the cylinder body vertically. Adding grease every two hours will ensure that the breaker's components stay lubricated and avoid damage to the hydraulic pump. If the lubricating grease is added when the steel braze is suspended, the grease will enter the striking chamber, causing abnormal high-pressure oil to be generated in the striking chamber during striking. This can cause damage to the hydraulic system and the hydraulic pump.
- Hydraulic Oil Volume and Pollution
The hydraulic oil's pollution status is one of the main causes of hydraulic pump failure. Therefore, it is essential to confirm the pollution status of the hydraulic oil in a timely manner. Hydraulic oil should be replaced every 600 hours, and the core should be replaced every 100 hours. Lack of hydraulic oil can cause cavitation and lead to hydraulic pump failure, breaker piston cylinder strain, and other issues. Therefore, it is suggested to check the oil level before daily use.
- Replace the Oil Seal in Time
The oil seal is a vulnerable part of the hydraulic system, and it is recommended to replace the breaker oil seal after approximately 600-800 hours of operation. When the oil seal leaks oil, it must stop working immediately and replace the oil seal. Otherwise, dust can enter the hydraulic system and damage the hydraulic pump and other components.
- Keep the Pipeline Clean
When installing the breaker pipeline, it must be thoroughly cleaned, and the inlet and outlet oil circuits must be connected circularly. When replacing the bucket, the breaker pipeline must be blocked to keep the pipeline clean. Keeping the pipeline clean will prevent debris and contaminants from entering the hydraulic system, which can cause damage to the hydraulic pump and other components.
In conclusion, an excavator equipped with a breaker is a powerful tool that can be incredibly useful when used correctly. However, it is essential to take proper care of the hydraulic pump to ensure the longevity and effectiveness of the excavator. Proper engine speed, buttering posture, frequency and quantity, hydraulic oil volume and pollution, oil seal replacement, and pipeline cleanliness are critical factors in protecting the hydraulic pump when operating an excavator with a breaker. By following these guidelines, you can ensure that your excavator is well-maintained and functioning at its best.
